Unable to access some web application through one of wfe server.

Hi,

We have different WFE servers in our SharePoint environment. To make sure that our every WFE server is working fine we check it through making entry in host file and access the web application/top site collections. We are able to access through all WFE server but from one server it is not working. We have 5 web application but we are able to access only 2 and for three we are getting error.I am attaching the error message when receiving at opening the page. I checked event viewer and saw some ASP.net error.
